+This demo shows Drand and Drop using a custom data type and a custom data object.  A type called "DoodleLines" is created and a Python Pickle of a list is actually transfered in the drag and drop opperation.
+
+A second data object is also created containing a bitmap of the image and is made available to any drop target that accepts bitmaps, such as MS Word.
+
+The two data objects are combined in a wxDataObjectComposite and the rest is handled by the framework.
